执行步骤

Execution Steps

步骤 1: 理解筛选条件

Step 1: Understand Screening Conditions

解析用户的自然语言，提取筛选条件：

市场范围：A 股/港股/美股/某板块
涨跌幅条件：涨幅 > X% / 涨停 / 跌停
估值条件：市盈率、市净率范围
规模条件：市值范围
成交条件：成交量、换手率
排序要求：按什么排序，取多少条

Parse the user's natural language and extract screening conditions:

Market Scope: A-shares/Hong Kong stocks/US stocks/certain sector
Price Change Conditions: Increase > X% / daily limit / limit down
Valuation Conditions: P/E ratio, P/B ratio range
Scale Conditions: Market capitalization range
Trading Conditions: Trading volume, turnover rate
Sorting Requirements: Sort by what, take top N stocks

步骤 2: 获取全市场数据

Step 2: Obtain Entire Market Data

根据市场范围调用对应的批量查询工具：

A 股：

json

{
  "tool": "get_all_a_share_quotes",
  "arguments": {
    "market": "all"  // 或 "sh"/"sz"/"kc"/"cy"
  }
}

港股：

json

{
  "tool": "get_all_hk_quotes",
  "arguments": {}
}

美股：

json

{
  "tool": "get_all_us_quotes",
  "arguments": {
    "market": "all"  // 或 "NASDAQ"/"NYSE"
  }
}

板块成分股：

json

{
  "tool": "get_concept_constituents",  // 或 get_industry_constituents
  "arguments": {
    "code": "板块代码"
  }
}

Call the corresponding batch query tool based on the market scope:

A-shares:

json

{
  "tool": "get_all_a_share_quotes",
  "arguments": {
    "market": "all"  // or "sh"/"sz"/"kc"/"cy"
  }
}

Hong Kong Stocks:

json

{
  "tool": "get_all_hk_quotes",
  "arguments": {}
}

US Stocks:

json

{
  "tool": "get_all_us_quotes",
  "arguments": {
    "market": "all"  // or "NASDAQ"/"NYSE"
  }
}

Sector Constituents:

json

{
  "tool": "get_concept_constituents",  // or get_industry_constituents
  "arguments": {
    "code": "sector code"
  }
}

步骤 3: 数据筛选

Step 3: Data Screening

对获取到的数据按用户条件进行筛选：

javascript

// 示例筛选逻辑（AI 内部处理）
const results = allQuotes.filter(stock => {
  // 涨幅条件
  if (条件.minChangePercent && stock.changePercent < 条件.minChangePercent) return false;
  if (条件.maxChangePercent && stock.changePercent > 条件.maxChangePercent) return false;
  
  // 市盈率条件
  if (条件.maxPE && stock.pe > 条件.maxPE) return false;
  if (条件.minPE && stock.pe < 条件.minPE) return false;
  
  // 市值条件（单位：亿）
  if (条件.minMarketCap && stock.totalMarketCap < 条件.minMarketCap) return false;
  
  return true;
});

Filter the obtained data according to user conditions:

javascript

// Example screening logic (processed internally by AI)
const results = allQuotes.filter(stock => {
  // Price change condition
  if (condition.minChangePercent && stock.changePercent < condition.minChangePercent) return false;
  if (condition.maxChangePercent && stock.changePercent > condition.maxChangePercent) return false;
  
  // P/E ratio condition
  if (condition.maxPE && stock.pe > condition.maxPE) return false;
  if (condition.minPE && stock.pe < condition.minPE) return false;
  
  // Market capitalization condition (unit: 100 million)
  if (condition.minMarketCap && stock.totalMarketCap < condition.minMarketCap) return false;
  
  return true;
});

步骤 4: 排序和限制

Step 4: Sorting and Limiting

按用户要求排序并取前 N 条：

按涨幅排序：

sort((a, b) => b.changePercent - a.changePercent)

按成交额排序：
```
sort((a, b) => b.amount - a.amount)
```

按市值排序：

sort((a, b) => b.totalMarketCap - a.totalMarketCap)

Sort according to user requirements and take the top N stocks:

Sort by price change:

sort((a, b) => b.changePercent - a.changePercent)

Sort by trading amount:
```
sort((a, b) => b.amount - a.amount)
```

Sort by market capitalization:

sort((a, b) => b.totalMarketCap - a.totalMarketCap)

步骤 5: 输出结果

Step 5: Output Results

以表格形式输出筛选结果：

Output the screening results in table format:
